And the fact that we are almost on the top of the world makes it very apparent that the world is round.
In the winter time, I saw the sun creep above the horizon, and I stood on a hill looking at the little bit of sun amazed by the fact that I am almost standing tangent to it. Now in the summer, the sun has climbed it's way from setting and rising in the south to rising and setting in the north.
Other natural phenomenon that are related to just living up here like the aurora, and from what distance can you see it. Since it is like 1000km up in the sky you can see it from pretty far away. But do you need to look north to see acting like a wall to the horizon, or do you need to crank your neck up 90 degrees because you are directly underneath of it? Or say, if you are down in Kodiak or Ketchikan and faintly see it on the horizon? Because where and how you can see the aurora is very dependent on the fact that the earth is round.
